Thank you for your cooperation.Long-term closure of a lane on route 117 south
The Ministère des Transports et de la Mobilité
durable would like to inform the public that due to work being carried out by
the town of Sainte-Thérèse, the right lane of Route 117 (Labelle Boulevard)
southbound will be closed until December 19 at 11:59 p.m.
The closed section is located on Île Bélair,
upstream from the Marius-Dufresne Bridge (which connects Rosemère to Laval).
Work may be postponed, extended or cancelled
due to adverse weather conditions or operational constraints.
The Ministère thanks road users for their
cooperation. For the safety of both road users and workers, it is essential to
respect the signage in place.
Work at the Sainte-Thérèse drinking water purification plant beginning November 11
Major work will begin at the Sainte-Thérèse drinking water purification plant on November 11, 2025. The work will continue until approximately early December. This work is essential to improve the resilience of the network and better isolate pipes in the event of future breaks.
No impact is expected if the work proceeds as planned. However, due to the complexity of the work, an incident on the main pipe could temporarily interrupt the water supply. A precautionary boil water advisory would then be issued for the entire area served by the purification plant.
The Town will contact affected residents and businesses.

newsletter.

Reconstruction of Île-Bélair bridge is completed
On June 27, the Ministère des Transports et de la Mobilité durable announced that the reconstruction of the Île Bélair bridge is now complete.
The reconstruction project involved replacing the structure with an almost entirely prefabricated factory-built structure, and adding a multi-use path linked to the municipal network to provide users with a safe active transportation link. This innovative method reduced the impact on road users and local residents, particularly in terms of the number and duration of traffic obstructions.
For full details of the work carried out, consult the press release (French only) issued by the Ministère des Transports et de la Mobilité durable.
WORK ON HIGHWAY 15 BETWEEN HIGHWAY 640 AND 50
The Ministère des Transports et de la Mobilité durable wishes to inform road users that work to build a new left-hand lane on Highway 15 between Highway 640 and 50 will begin on June 6, 2023, and will be spread over a three-year period. This new lane will be reserved for public transit, carpooling and emergency services.
Due to the nature of the work, complete and partial closures of Highway 15 northbound will be necessary throughout the construction period.
